How to connect data on a scatter plot in MatLab?

Hello,

I am trying to connect my data with a line. In my code I have the three points plotted, I just need them to connect. Also, if you know of a way to have my last plot be at the number of elements equal to Inf,that would help a lot, thanks. If you need to see all my code it's in the attachments.

Code:

figure;scatter(5,U5(n5+1),'m *')

hold on

scatter(10,U10(n10+1),'m *')

scatter(20,U20(n20+1),'m *')

xlim([0 30])

title('Deflection V. Number of Elements')

xlabel('Number of Elements')

ylabel('Deflection')

You could use the plot command instead. Something like

figure
plot([5 10 20],[U5(n5+1) U10(n10+1) U20(n20+1)],'m*-')

See the documentation for plot for details.
